To all whom it may concern:

Be it known that I, JOHN OSCAR EMRICH, a resident of Allegheny, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Metallic Doors; and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to a metallic or fireproof door, and hasfor its object the construction of such a door by combining sheet steel, wire glass and otherfire'retarding materials in a novel and effective manner for the purpose of forming such a door.

A further object of my invention is to effect such a result at an economical cost on account of the simplicity of construction of the steel parts, and of the manner ofcomelements used therewith.

The following is a-clear and concise description of my preferred form of construction, reference being had to the accompanying drawings, in which:

Figure 1 is a sectional elevation of my inventlon. Fig. 2 is a horizontal section on lines 2-2 of Fig. 1. Figs. 3 and 4 are similar views on lines 3-3 and lines 44 respectively of Fig. 1. Fig. 5 is a view in ers ec- .tive, showing the construction of t e oor particularly at the point of abutment or connection with the stiles. Fi 6 is a perspective view of a clamp adapte to bind together the rails and stiles. Fig. 7 is a perspective view of a section of a stile showing its construction and adaptability for engagement by the clamp. Fig. 8 shows, in erspective, a slotted pin fitted with keys and set screws. Fig. 9 is a plan or top view of a lock carrier or su port. r

ike references in the specification refer to like parts in the drawings, in which 1 represents an outer hollow stile.

2 represents, an outer hollow rail, both of which are preferably made of sheet steel, each having a mar inal angular formation 3 on each side thereo The adjoining or abutting parts of said outer stiles and rails being turned inwardly to'form the obtuse angles 4 (Fig. 5 and 7) which are adapted to be engaged by the clamps 5, as shown in Fi 3, being inserted through the opening 6 o the stiles 1 and open end 7 of the rail 2, the obtuse angles 4 and clamp 5 beirgg thoroughly clamped together to effect a pe ectjunction of the outer stiles and outer rails as shown in Figs. 1 and 3, after which the part8 is forced down closin the open corner 7 of the outer rail 2, and t e part 9 is forced over to close the open end 6 of the outer stile 1, the parts 8 and 9 bein held in fixed'closed osition bysuitable mac 'ne screws inserted t ough the holes 10 and engaging a suitable not (not shown) onthe under side of the parts 3 and 9. Within the outer stiles and rails are inner hollow stiles 11 and inner hollow rails 12,

each having a marginal angular formation surroundin the space between said inner stiles 1 1 and inner rails 12 and forming an inner frame 13. The innerstiles' and rails are made preferably of a size and form to be out 'of contact with the walls of the outer stiles and rails except at the hinge bearing points and marginal angle of the outer stile or rail where the inner stile is extended, folded and carried against the depressed hinge bearlngs point 14 on the outer stile 1 for the purpose of reinforcing those parts, as shown at 15, in

ittached to or carried by the inner stile is alock carrier or $11 port 16 (Fig. 9) ada ted to carry a lock independently of the outer stile, the opening 17 therein and the opening 18 in the outer stile permitting the communication between the lock and a keeper in a 'jamb. In each of said inner stiles and rails fire-retarding materials, preferably a sheet of Wire glass 19 and sheets of asbestos 20 one on each side thereof, the glass 1.9 and asbestos 20 being long'enough to occupy tho ends of the inner rails which are inortisod in the ends of the inner stiles and fixedly socured in position by the pins 21 having slots 22 therein and keys 23 held in position in the slots by set screws 24.'

In the inner frame 13 is a sheet of wire glass'25 which may be held in place by cleats 26 one end of which are secured to the angle 3 of the outer stiles and rails, the other end of said-cleats being arranged to bear against the sheet of glass to support the same (Fig. 4). The outer and the inner stiles and rails and the fire-retarding material within the inner stiles and rails are finally tied rigidly together by pins 21 being inserted through said structure at the angle 3, and keys '23 at both ends, the keys being secured in position by set screws 24, as heretofore described, (Fig. 4). The molding 28 is then put in position and readily secured thereinby suitable machine screws engaging the tapped hole 29.-

and rails, having outer stiles and rails, an inner frame formed around the margin of the space between the inner stiles, pins adapted to engage the stiles and rails, and means connected to the ends of the'pins for holding the parts in fixed position.
